The Schedule referred to in these Letters Patent making part of the same.

The opening 2, for supplying the oil-chamber B with oil, is so arranged, with relation to the oil-ways 0, that they can be cleaned out with ease and facility. A

The bore of the hub A is provided with recesses, intowhich arefitted gum washers, x, which fit closely and neatly around the axle O. The washers are used for the purpose of preventing the oil from flowing out at the ends of the hub of the wheel.

The hub is also provided with a recess, f, for receiving. oil as it flows on the axle from the ends of the hub toward its centre.

D represents the collar, or flange, on the axle. S represents the linchpin. The wheel and axle represented in the accompanying drawings are such as areused on the trucks of The advantage of our improvement consists in distributing the oil on axles at the points where itis most needed, and in saving oil, labor, and time, in oiling wheels, and in so arranging the opening for supplying the oil-chamber with oil, that the oil-ways may be cleaned out with ease and facility.

Having thus described our improvement for oiling wheels,

What we claim as of our invention, is
